I have already tried with lower PLL (from 1.5 to 1.7) and i get the same results. With 1.85, was the best i could do on LinX/OCCT Linpack as i mentioned on my last post.
As i remember from my old s775 platform, the skews did help in many cases, but here from what i read, you can face exactly the opposite (much instabillity) using high ioh/cpu skews. I think that it's too early (low bclk, just 206, i see that achieving this bclk is piece of cake on W3520/decent 920) to start messing with skews, but i guess i'll have to start with it.
Another think i need to ask is about the LLC. on 0% calibration, i get much vdroop. To be exact, from 1.3750@BIOS (1.360@real/idle, measured with polymeter) it goes around 1.308@full load. Is that normal? On the other hand, with full calibration, it overvolts quite a bit (1.3750@BIOS-1.381@real/idle-1.383@full load), which, from what i've read, its normal.
50% Calbration is trying to keep the balance between the other two, but i get a lot of spikes on vcore some times.
What you guys use on LLC? full or 50%?
UCLK was just a long shot, anything below x2 RAM will cause instability, hence why ASUS don't allow those values. It is often recommended that you have the UCLK set to (2x +1) RAM.

As for clock skew, I can't really comment on what other people have had, but I was able to pull off any extra 5MHz on the BCLK by using it, but tbh it isn't worth the trouble.

LLC, I did a mini study on it myself when I first got the board, plotted graphs etc in relation to the voltage measurements at different overclocks. I came to the conclusion that in low voltages, it's best to have it at 0% otherwise it overshoots by quite a bit. When you hit medium voltages (1.2-1.3 on my i7 930 for example) 50% worked best. After which Full calibration seemed to work best. If you use Full calibration on voltages below 1.35V then you will most likely see a negative impact. Regardless of what voltage you use, Full calibration always props it up a notch more, even if it is marginal; this is to guarantee no vDroop.
